SPECIFICATION forming part of Letters Patent No. 354,251, dated December14, 1886.

Application filed July 13, 1885.

Serial No. 171,517. (No model.)

To all whom it 17mg concern.-

Be it known that I, JOHN F. SEIBERLING, of Akron, county of Summit, andState of Ohio, have invented a new and useful Improvement inGrain-Binders, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification.

My invention relates to a novel construction and arrangement of theparts of the knotting mechanism, with a'view, mainly, to securinggreater compactness of the parts and a reduc- 11011 in the weight of thesaid mechanism as compared with constructions now in use. It will beunderstood from the following description, taken in connection with theclaims.

In the accompanying drawings, Figure 1 is an outer side elevation of myimproved k notting mechanism; Fig. 2, an end elevation of the same. Fig.3 is aplan view of the same, with the cam-wheel shown in section; Fig.4,, a face view of the cam-wheel detached; Fig. 5, an end elevation,looking from the end adjacent to the canrwheel, with said wheel removed;Fig. 6, aperspective view of the cordholder-carryin g arm and partsconnected therewith; Fig. 7, a similar View of the knotter, the endofthe jointed shaft to which it is attached, and of the pivoted framesupporting said end, with the knife attached; and Fig. 8, a side view ofthe parts shown in Fig. 7.

A represents the knotteractuating and camwheel shaft-5 A, the cam-wheelsecured to and rotating with said shaft.

C is a knotter-mechanism-supporting frame or casting, provided near itsupper end with a sleeve, C, surrounding the shaft A, and at its lowerend with afoot-flange, 0 through which, in practice, it is bolted to theknotter-shield or breast-plate, the shaft A serving to uphold thecasting 0 and the end of the breast-plate connected therewith, while thelatter prevents said frame or casting from turning with or upon theshaft A, in a manner well understood. The frame or casting G is providedwith arms 0 and 0, extending obliquely upward and outward, formingsupports for the rock-shaft or pivot on which the cord-holdercarryingarm D is suspended, and at c with a slightly-inclined upright sleeve-bearing for the upper portion of the inclined and jointed knotter-shaftB, which is arranged at one side of the sleeve 0 of theknotter-mechanism frame, crossing the horizontal plane of .the shaft A,as will be explained. Thelower pivoted portion, B, of the knotter-shafthas the knotter -hook B secured to it, and is journaled in a frame, E,pivoted by means of a rock-shaft or pivot, E, formed upon it, in atransverse sleeve, 0*, formed in the frame 0, so arranged that when theknotter-shaft is in position to be flexed th'e jointb therein will be inline with said pivot E. By this arrangement of the knotter-shaft tocross the plane of its actuating-shaft upon one side it is made toassume a position substantially tangential to the latter, or to thesleeve 0, in which it rotates, and to accommodate this arrangement theteeth of the segment a on the camwheel A have a corresponding tangentialor spiral arrangement given to them, (shown in Fig. 4,) instead of theradial arrangement usually employed, and by setting the shaft to inclinerearward or outward and away from the adjacentpperative face of thecanrdisk from its upper end, to which the actuating-pinion B" isattached, downward, its lower end, to which the knotter is attached, issufficiently removed from the cam-Wheel A to permit the needle, the endof which is indicated at F, to pass between said shaft and the wheel, asshown in Fig. 1. The needle in practice is secured to and operated bymeans of a rockshaft geared to and having its movements timed to thoseof the shaft actuating the knotter mechanism, and is arranged preferably'to operate from beneath the binder-table, in a manner well known.

The frame or arm D, carrying the cordholding devices, is shown in Fig.6. It is provided at its upper end with a fork, the arms ddof whichterminate in eyes or short sleeves, which suspend it from a rock'shaft,D, supported in the arms 0 and 0 of the frame 0, the

fork striding a tubular rock-shaft, D'", mounted and turning on the samepivotal center or rock-shaft 1). The forward arm, (1, of the fork has alaterally-projecting fork or arms, (I (2, formed on its side adjacent tothe shaft A, said fork striding the latter and a cam projection, a, onthe hub of the ca1n-wheel, the latter servingby its action on said armsat d to impart a lateral vibration to the arm D in each revolution ofthe shaft Aand cam-wheel A, for yielding cord to the knotter, in amanner well understood.

The cord-holding disk G is mounted upon a stud-pivot, g, secured to thelower end of the vibrating arm D, and upon this same pivot, between thedisk G and the arm D, is pivoted an arm or lever, 9, adapted to swing onsaid pivot, and provided near its swinging end with apin, g", to whichthe lower end of a connecting rod or pitman, H, is attached, the upperend of said rod being connected with a wrist-pin, i, on a crank-arm, Dkeyed or otherwise secured to the rock-shaft D. The forward end of shaftD has a crank arm, D", formed upon it, provided at its outer end with awrist-pin havingafriction-roller, i, mounted upon it, which runs in thecam-groove A in wheel A, and which serves at each revolution to Vibratethe rock-shaft D, and thereby to impart a vertical vibration to thelever g. The lever extends beyond the pin 9', and has a pawl, 9 pivotedto its outer face, adapted to engage notches in the cord-holder disk G,for imparting an intermittent rotary movement thereto, and adapting itto carry the cord into the cord-holding shoe G, in a manner wellunderstood. The pawl g is held in engagement with the notched diskordinarily by its own gravity, which permits it to back freely over theface of the disk when the arm g is depressed for moving the pawl intoposition to again act on the disk; but to insure its engagement with thelatter it is provided on its upper face with a spur, g, which projectslaterally over the end of lever g, and which, when thelatter isdepressed, comes in contact with a spring, H, secured to the rod H, andwhich serves to force the pawl into engagement with the disk foractuating the latter. The spring H at its lower free end overhangs theend of the lever g, and as it rises with the rod H, after having forcedthe pawl into engagement with the disk, it passes off the spur g, andrests on said end of lever g, leaving the pawl freeto risein backingover the notched periphery of the disk held down by gravity only, asexplained.

The shoe G consists of a pendent curved bar or plate pivoted at itsupper end to a laterally-projecting lug or ear, j, on the frame or armD, near the upper end of the latter, and provided at its lower end witha groove or parallel ribs, in or between which the edge of thecord-holding disk G moves for engaging and holding the cord. The shoe Gis provided at its lower end on its side or edge with alaterally-projecting spur, against which thelower free end of a spring,H bears for holding the shoe up against the action of the diskGwith-thedesired pressure. This spring is secured, by means of a set-screw oradjusting-bolt, to the forward face of a laterallyprojecting lug or ear,j, formed on the arm D,

below and slightly in rear of the lug j, as

- shown. The upper end of this spring H is curved slightly inward towardits supportinglug at h in such manner as to rest upon and hold the bodyof the spring away from the face of the lug, thereby permitting theadjustment of the set-screw, and the consequent tension or pressure ofthe spring on the spur g, asdesired.

The tubular rock shaft or sleeve D is mounted on the rock-shaft D,between the arms D and D thereofland between the arms d d of thecord-holder arm D, as explained, and has on its forward end a curved armor hood which overhangs the arm (I, and is provided with a crank-arm, Dhaving a forwardly projecting pin carrying a frictionroller, '5 whichprojects within the camgroove A and causes a vibratory movement of thearm D and sleeve D? at each revolution of the cam-wheel. The sleeve Dsurrounds the rockshaft D, and is supported thereby and by the forwardarm, 0, of the frame (7, said arm having an enlarged bearing, providedwith a removable halfbox, 0 (see View of said halfbox detached in Fig.5,) facilitating the removal and replacement of the sleeve D and shaftD. The rear end of the sleeve D has a crank-arm, D, formed upon it,provided with a rearwardlyprejecting pin, d, from which aconnecting-rod, k, extends downward to a perforated lug or ear, 0, 011the rear face of the pivoted arm E, on which the lower pivoted end ofthe knotter-shaft is journaled. The joint in'the knotter-sha t B B isinline with the pivot E, on which the arm E is supported, and as thelatteris vibrated or swung back on said pivot by the action of the camwheel onthe sleeve D and the connections of the latter therewitlnthe knotterwill be carried with it for withdrawing its point from the loop formedin the knot, and thereby freeing the bundle. The arm or frame E has theknife 0 for severing the cord, secured to and moving with it, andarranged to sever the cord, and thereby to free the bundle as the armswings backward to withdraw the knotterpoint from the loop. The arm orframeEhas a cam projection, 6", formed on its lower face, which, in therotation of the knotter-shaft to form the loop on the knotter, serves toopen the jaws of the knotter to receive the ends of the band, said camacting on a roller, Z, on a.

heel projection of the movable jaw of the knotter for that purpose. Anarm, E on the swinging arm or frame Ehas a' pendent spring,

L, secured to it, which extends down in rear of the knotter B and actsupon a roller, Z, mounted on a heel-extension of the moving jaw thereoffor holding the latter snugly against the fixed jaw while the knotter isbeing vibrated to free it from the loop. The pinion B" on theknotter-shaft has the usual delay surface, B, formed upon it, whichoperates, in connection with the rear face, a, on' the cam-wheel to holdthe knottershaft against rotation, except when acted on by the toothedsegment a,- but the mechanism being in these and other details ofconstruction similar to others in common use, and not being hereinclaimed,need not be described.

IIO

It will be apparent from the foregoing description that the arrangementof the jointed knotter-shaft, whereby it is made to cross the plane ofits actuating or cam wheel shaft, and at an inclination to the face ofthe cam-wheel, so that while operated thereby through a pinion on oneend its opposite end will be sufficiently removed from said cam-wheel topermit the free passage of the needle between,

said shaft and the face of the cam-wheel, enables me to bring theknotting mechanism into very compact shape-a very desirable feature inpractice, and one constituting the main object of my presentconstruction, as explained.

Having now described my invention, I claim as newl. The combination,with the cam-wheel, of the knotter-shaft crossing the plane of theknotter'actuating shaft and the face of said wheel, and inclinedlaterallyin relation to and actuated by the latter, and the needlearranged to pass between said knotter-shaft and the camwheel,substantially as described.

2. The spiral segmental gear on the camwheel, in combination with theknottershaft crossing the plane of the cam-wheel shaft and inclinedlaterally to the face of the cam-wheel, and having its actuating-pinionlocated on one side of said cam-wheel shaft and the knotter on theopposite side thereof, substantially as and for the purpose described.

3. Thecombination, with the cam-wheel and the shaft supporting andactuating it, of the knotter-shaft having its actuating-pinion on oneend and the knotter-hook on the other, and arranged in close proximityto and crossing the plane of the cam-wheel shaft in laterally-inclinedrelation to the face of the camwheel, and the spiral segmental gear onthe cam'wheel for actuating said knotter-shaft, substantially asdescribed.

4. The jointed knotter-shaft, in combination with the vibrating hingedarm or frame E, carryingtheswinging end or part of said shaft, a cam foropening the knotter-j aw, and aknife for severing the cord, andmechanism, substantially as described, for vibrating said arm or frame,and the hinged part of theknotter-shaft journaled thereon, substantiallyas described.

5. The combination of the cam-wheel A, the shaft D, and tubular shaft orsleeve D mounted and turning on said shaft D, the vibrating arm or frameE, knotter B, and corddisk G, and their supporting and actuatingdevices, substantially as described, whereby said knotter and disk areboth vibrated from the same cam.

6. The rock shaft D and rocking sleeve D,

mounted thereon, both connected with and adapted to be operated by thesame cam, in combination with the cord-holder arm supported by andVibrating on said shaft, the swinging arm carrying the knotter, and theknife for severing the cord, and mechanism, substantially as described,for actuating said cord-holder and knotter-carrying arms.

7. The combination of the cord-holding disk, its actuating-pawl y theconnectingrod H, and the spring H arranged to be disengaged from saidpawl when the latter is raisedin operating the disk, and to be broughtinto contact therewith when the pawl isdepressed, substantially asdescribed.

8. The combination of the jointed knottershaft and the hinged arm orframe supporting the swinging end of said shaft, the joint in the shaftand the frame-pivot being arranged to coincide, substantially asdescribed.

9. The swinging cord-holder arm or frame provided with the fork or armsd and d, and the cam on the cam-wheel shaft for actuating the same, incombination with the hinged arm of the knotter-frame carrying the hingedend of the knotter-shaft, knotter, and means, substantially asdescribed, for vibrating said hinged arm of the knotter-frame andknotter.

In testimony whereof I have hereunto set my hand this 1st day of July,A. D. 1885.
